damon69 Posted August 13, 2013 Share Posted August 13, 2013 Hi folks, thanks for taking the time to read this. Any help or advice is most appreciated! My Rig is about a year and a half old, and has been a tremendous pleasure to build, tweak, mod, and overclock. However a couple of recent upgrades may have exposed a problem with my 1200i. I switched out a pair of ASUS HD 7850s XF in favor of first one, and later a second Gigabyte HD 7970 XF. Now Open Hardware Monitor and AIDA64 Extreme are showing my 3.3v Rail running at 3.296v. Until three days ago I had not seen any of the Rails dip nearly so much. I had enjoyed pretty rock solid numbers. My 12v and 5v Rails are also lower than they were, now running right at 12.0v and 5.0v under load. Before they maintained 12.096v, 5.049 and 3.36v during load. I realize that I'm worrying about tiny fluctuations, however I thought that such a high end, much touted 1200w PSU with such serious components and hefty Rails wouldn't be challenged by a system which is only pulling maybe 840w-900w at the absolute outside. Is this what should be expected? Or am I looking at a PSU in decline? Its actually my second PSU for this Rig so its only been running for about 6 months. My Rigs details will follow, and thank you again for your help and advice! i7 3770K(DeLid) @ 5.0GHz w/ 1.395v | 16GB (4x4) G. Skill 2666 TridentX @ Stock | ASUS MVF BIOS 1803 | 2x Gigabyte HD 7970 OC XF Mild OC locked voltage | 1 840 Pro 256 2 840 Pro 128 SSDs | WD BC 2TB HD | 16x BluRay RW | DVDRW | EK Custom Loop 1 Pump | 15 120mm Gentle Typhoons & Corsair PWM HP | Corsair 1200i ... I think that is everything that sucks power. Its all in a 900D and runs off of an APC Back UPS Pro I am tempted to try the little gizmo I bought awhile back that allows 2 PSUs to run together. Maybe put all of my fans, pump, and maybe GPUs on my 850w Corsair PSU. But geeze, I really hoped that I was buying the King Kong of PSUs when I got the 1200i... crap :[pouts: Link to comment Share on other sites More sharing options...
